Hand 1: Snap call.

Hand 2: Your 1/2 pot flop bet is weak. He shoves on the river with 90BB? Given stack sizes, easy call.

Hand 3: Re-raise PF to 24BB, snap call the chaser.

Hand 4: 3bet this villian...he's weak/tight if this turn helped him at all. You have top two, and he'll likely fold like a lawn chair. You can fold if he plays back at you.
